PUMP.

SPECIFICATION forming part of Letters Patent No. 651,688, dated June 12,1900.

Application filed March 24, 1900. Serial No. 10,049. (No model.)

T0 ctZZ whom it may concern).-

Be it known that I, JOSIAH S. ALBRIGHT, a citizen of the United Statesof America, residing at Van Wert, in the county of Van Wert and State ofOhio, have invented new and useful Improvements in Pumps, of which thefollowing is a specification.

One object of this invention is to provide an improved pump by which thewater is lifted and discharged from the spout through the medium of anauxiliary air-pump which is connected to the main pump-cylind er, thesaid air-pump lifting the water into the main pump-cylinder upon theupstroke of the piston and discharging the water'upon the downstroke ofsaid piston.

A further object of the invention is toprovide a peculiar constructionof pump-valves by means of which the water is permitted to leak past thevalves when the latter are at rest, so that the water will readily drainfrom the body of the pump and prevent freezing.

With the above objects in view the invention consists in the peculiarconstruction and combination of parts comprising the pump, all as willbe hereinafter fully set forth, and specifically pointed out in theappended claims.

In the accompanyin g drawings, which form a part of this specification,and in which like letters of reference indicate similar parts throughoutthe several views, Figure 1 is a side elevation of a pump constructed inaccordance with my invention. Fig.2 is a vertical sectional view throughthe pump. Fig. 3 is an enlarged detail view of one of the pump-valves.

Referring to said drawings,A designates the main pump-cylinder, which isprovided at its ends with flanges a a, to which are bolted a top plate Band the flanged upper end a of the well-pipe C. At one side of thecylinder A is formed an outlet pipe or elbow D, the

upper end of which is provided with a flange d, to which is bolted acylinder or valve casing E, and to the upper end of this cylinder orvalve casing is bolted the discharge-pipe or pump-stock F, terminatingin a spout G. In the lower ends of the cylinders A and E are locatedball-valves H and 1, respectively, the movement of said balls off theirseats being limited by means of webs 8, formed inthe to a bracket M,projecting therefrom.

cylinders, said webs also directing the balls onto their seats andinsuring the passage of the water around said balls. The seats of theball-valves are of peculiar construction for the purposes of theinvention, and as they are similar a description of one will apply toboth. Said improved valve-seat is made up of a bent plate K, the uppermember 7t being narrower than the lower member 7a and lies normallyabove the same to permit water to pass around said upper member andthrough the opening in the lower member for the purpose hereinafterexplained. The member 7; of the seat is also adapted to close down uponthe lower member to form a tight valve dur- -ing the operation ofpumping, and though both members are provided with central openings forthe passage of the water when the ball is off its seat the said ball isadapted to fit into the opening of the upper member. The saidvalve-seats are held in place as shown in the accompanying drawings.

L designates the air-pump, which is located in the rear of thepump-stock F and is bolted The cylinder of the air-pump is connected tothe upper end of the main pump-cylinder A by a vertical pipe N, which isa comparativelysmall pipe, and working in the cylinder of the air-pumpis a piston 0, connected by a rod P to a lever or pump-handle R, thelatter being pivoted at its inner end to earst of a twopart collar T,bolted on the pump-stock. The inner end of the lever or handle isbifurcated to embrace the pump-stock and bring the pivot-point in frontof said pump-stock, so that the desired movement can be imparted to thepiston of the air-pump without requiring an excessive movement of theoperating end of said lever or handle.

In the operation of the pump the upstroke of the piston of the air-pumpdraws the water into the main cylinder A, past the ball valve H, andupon the downstroke of said piston the valve H closes and the water isforced past the valve I and into the dischargepipe, it being understoodthat the valve I closes upon the upstroke of the piston to prevent backpressure in the discharge-pipe. It will also be noted that during theoperation of the pump the pressure upon the ball-valves ,ter is beinglifted.

"quickly closes the member 7c of the valveseat upon the" member 70', andthereby prevents any leakage around the valves. When the pump is atrest, however, the members 7c of the val ve-seats,, being relieved ofpres- .sure, will rise slightly and permit the water to leak through thevalves, and thereby drain the body of the pump. Thisis particularlydesirable in winter, as it will drain all the amined or repaired in caseit should get out of order. The particular construction and arrangementof the valves also insures their perfect operation while the pump is inuse,

forming tightvalves, while'they also provide for ,draining the dump whenit is at rest,

Havingthus described my invention,"what I claim as new, and desire tosecure by Letters Patent, isr i 1. In a pump, thecombination, of thecylinders A and E connected to each other and to the well-pipe anddischarge-pipe, respec-j mally separated, said parts havingo penings 2;Aball-valve for a pump, comprising, in

combination with the ball, a plate bent upon itself to present two partsnormally separated and provided with openings, the ball being adapted toclose one, of the openings, substantially as shown, and for the purposeset forth.

3. In a pump, the combination, of'the cylinders A and E connected toeach other and to the .well-pipe and discharge-pipe, respectively,ball-valves located in the bottom of saidcylinders and closing downward,and valve-seats for the balls comprising abent plate" presenting twoparts normally separated; together with an air-pump supported adjoiningthe pump-stock, a collar attached to the pump-stock and havingears-located on the opposite side of said pump-stock from the air-pump,and a pump-handle having a bifurcated lever pivoted to the aforesaidears, the pump-handle being connected to the piston-rod of the air-pump,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
